The Laboratory: Present Activities, Research & Development Projects

Aleksei Tepljakov

About Us

  • We are committed to research and development of Virtual and Augmented Reality applications.
  • As a scientific establishment, our main goal is to do research of Virtual Reality, its physiological and psychological aspects, applications, and its impact on products and services providing immersive experiences.
  • The laboratory has grown out of Alpha Intelligent Control Systems Research Laboratory, the members of which have diverse academic backgrounds and experience, including, but not limited to...

Our Goals

  • Having diverse backgrounds and experience, our team is ready to tackle the challenges put forth by the emerging field of VR and AR applications.
  • As we have deep roots in the academia, we also aim to develop and enhance existing Information Technology university study programs.
  • We also want to allow involved students, university personnel, as well as laboratory visitors to experience Virtual Reality and to encourage and improve their creative skills.
  • We envision that this will lead to development of synergy between different research and development groups and will enhance interdisciplinary collaboration and improve promotion of emerging technologies.

Business relations

  • We highly value relations with business establishments. We expect that existing companies will find VR a very attractive tool for developing cutting-edge real-life business applications.
  • What we offer is consulting services and assistance with fulfilling your business needs by means of this novel technology. We also offer academic collaboration, in case your current VR or AR related projects demand it.

Current R&D Projects

Synesthesia in Virtual Reality

Synesthesia in Virtual Reality

  • Synesthesia is the act of experiencing one sense modality as another, e.g., a person may vividly experience flashes of colors when listening to a series of sounds.
  • Recent technological advances in the Virtual Reality field allow to induce such experiences due to the effect of presence achieved in the virtual environment.
  • This has numerous medical and artistic applications.
  • In the current contribution, we focus on localization and visual interpretation of sound in Virtual Reality.

Sound localization

  • We use a conical array of microphones.
  • Our proposition is to use a DOA method, since compared to SRP-PHAT it avoids frequency domain computations and is thus more efficient in terms of performance.
  • Furthermore, the proposed DOA method allows to reduce the number of microphone pairs for cross-correlation.

Sound Visualization

  • In the VR environment the incoming sound waves are visualized as spheres moving towards the listener.
  • The color, size, velocity of travel, and sampling rate for generating the spheres can be determined experimentally.
  • The incoming waveforms are broken down into frames and analyzed as discussed previously.

Control Objects in Virtual Reality

Control Objects in Virtual Reality

  • The project is dedicated to creating virtual control objects for real-time control experiments.
  • We model laboratory objects, because this allows us to obtain highly accurate mathematical models of these systems for making classroom instruction much more efficient.
  • One specific goal is to mathematically model and implement physically accurate interactions between the user and the control objects (e.g., using motion controllers).
  • Future goals include modeling real-life industrial objects for implementing specialized virtual training.

Example: Maglev System (model)

Example: Maglev System (UE4)

Example: The 3D Crane demo

Virtual City Modeling

Virtual City Modeling

  • The long-term goal of the project is to model large-scale housing and transportation environments.
  • The specific focus is on Virtual Reality applications: virtual driving and urban orientation courses, architectural walkthroughs, virtual traveling guides.
  • The initial contribution was done by a group of students for their B.Sc. theses whereby a part of a district in Tallinn, Estonia, was recreated in Unreal Engine 4.
  • A tool for automating the task of modeling complex roads with respect to the landscape is currently being developed.

Example: Lasnamäe Demo

Example: Fitting Road Segments
